[0036] like Figure 1 As shown in ~5, an aircraft tire torque generator device includes: a torque assembly 1, which is L-shaped, and a torque device 13 for fastening the bolts and nuts of the tire 41 hub assembly is provided thereon.

[0037] Positioning component 2 is set on one side of torque component 1. After the tooling frame 25 of positioning component 2 rotates at a certain angle, it picks up tire 41, positions the wheel hub of tire 41, and forms the tire wheel hub assembly 4 to be fastened.

[0038] The tire 41 wheel hub assembly has a structure in which the upper and lower end faces of the wheel hub hold the tire 41 in the middle. The tire wheel hub assembly 4 needs to be fastened together with bolts and nuts.

[0039] The conveying component 3 is located below the torque component 1 and is used to transport the tire 41 to one side of the positioning component 2 so that the positioning component 2 can pick up the tire 41.

[0040] The torque assembly 1 includes a column 11, a crossbar 12, and a torque generator 13.

[0041] The column 11 is fixed to the ground, providing a stable foundation support for the entire torsion assembly 1.

[0042] The crossbar 12 is rotatably connected to the column 11 and is perpendicular to the column 11. The torque is set on the crossbar 12. The crossbar 12 is perpendicularly connected to the column 11 and can rotate around the column 11, so that the torque device 13 on the crossbar 12 can reach different working positions.

[0043] Once the tire 41 hub assembly is positioned by the positioning assembly 2, the crossbar 12 of the torque assembly 1 moves to the appropriate position, aligning the torque generator 13 with the bolt 262 to be tightened. The torque generator 13 activates and tightens the bolt 262 according to the preset torque value. After completion, the crossbar 12 returns to its original position, ready for the next operation.

[0044] The positioning assembly 2 includes a guide column 21, a lifting frame 22, a lifting cylinder 23, a rotating cylinder 24, and a tooling frame 25;

[0045] Guide column 21, fixed to the ground, provides guidance for lifting frame 22, ensuring that it maintains linear motion when moving up and down.

[0046] The lifting frame 22 passes through the guide column 21 and can move up and down under the drive of the lifting cylinder 23. The lifting frame 22 passes through the guide column 21 and is driven by the lifting cylinder 23 to achieve up and down movement. It carries the rotating cylinder 24 and the tooling frame 25 and is responsible for lifting the tire hub assembly 4 to the working height where the torque generator 13 can work.

[0047] The rotating cylinder 24, located at one end of the lifting frame 22, can drive the tooling frame 25 to rotate 90 degrees. The rotating cylinder 24 drives the tooling frame 25 to rotate 90 degrees, which in turn drives the wheel hub tooling 26 to rotate 90 degrees, facilitating the installation of the tire 41.

[0048] Tire 41 is usually placed upright in the tire storage area. After being suspended onto the conveyor trolley 31 by a crane, tire 41 is also placed upright on the conveyor trolley 31. Therefore, after rotating the wheel hub fixture 26 by 90 degrees, the tire 41 is pushed onto the wheel hub fixture 26 by the conveyor trolley 31. After the tire 41 is installed, the wheel hub fixture 26 is rotated 90 degrees to install the upper plate 42 (upper end face of the wheel hub).

[0049] A fixture 25, mounted on the rotating rod of the rotating cylinder 24, houses a wheel hub fixture 26 for accommodating and positioning the tire 41 rim. The wheel hub fixture 26 supports the positioning of the tire 41 rim and can be replaced with different models to accommodate various sizes of tire 41 rims.

[0050] The wheel hub fixture 26 includes several positioning sleeves 261, which are used to install bolts 262. The wheel hub fixture 26 is detachably mounted on the fixture frame 25 and is used to install wheel hub assemblies of different models of tires 41.

[0051] The conveying assembly 3 includes a conveying trolley 31 and a track. The conveying trolley 31 moves on the track and is used to transport the tire 41 to one side of the positioning assembly 2. The conveying trolley 31 is equipped with support rollers to ensure that the tire 41 does not sway from side to side during transportation, thus ensuring the stability of transportation.

[0052] Operating procedures for aircraft tire torque converter

[0053] 1. Equipment Preparation

[0054] Ensure that all components of the torque machine (torque assembly 1, positioning assembly 2, and conveying assembly 3) have been installed and tested.

[0055] Select the appropriate wheel hub fixture 26 according to the model of the wheel hub 41 to be installed and install it on the fixture frame 25 of the positioning component 2.

[0056] Place bolt 262 into the sleeve of hub tool 26.

[0057] 2. Transport tire 41

[0058] First, use a crane to lift the lower part 43 (lower end face) of the wheel hub onto the wheel hub fixture 26, and then lift the tire 41 onto the conveyor trolley 31.

[0059] The transport trolley 31 moves on the track, transporting the tire 41 to one side of the positioning assembly 2. The support rollers on the transport trolley 31 restrict the lateral movement of the tire 41, ensuring that the tire 41 remains stable during transport.

[0060] 3. Tire alignment 41

[0061] The lifting cylinder 23 of the positioning component 2 drives the lifting frame 22 to move up and down to adjust to a suitable height.

[0062] Rotating the hydraulic cylinder 24 causes the tooling frame 25 to rotate 90 degrees, so that the wheel hub tooling 26 is aligned with the delivered tire 41.

[0063] The conveyor trolley 31 moves forward again, and the tire 41 is fitted onto the lower piece 43 of the wheel hub and positioned in the correct position.

[0064] The rotating cylinder 24 rotates in the opposite direction, and the wheel hub fixture 26 rotates 90 degrees in the opposite direction under the drive of the fixture frame 25, so that the lower part 43 of the wheel hub and the tire 41 are horizontally upward.

[0065] The suspension machine lifts the upper piece 42 of the wheel hub onto the tire 41, accurately positions it, and forms the tire 41 wheel hub assembly to be fastened.

[0066] 4. Fastening bolt 262

[0067] The lifting frame 22 rises to below the torque generator 13 under the drive of the lifting cylinder 23.

[0068] The crossbar 12 of the torque assembly 1 is rotated to the appropriate position so that the torque generator 13 is aligned with the bolt 262 nut on the wheel hub assembly of the tire 41.

[0069] Torque generator 13 is activated to apply precise torque to each bolt 262 nut, ensuring the safety and reliability of the connection.

[0070] After tightening is completed, torque device 13 stops working, and crossbar 12 rotates to its initial position, ready for the next round of operation.

[0071] 5. Installation complete.

[0072] The transport trolley 31 transports the installed tire 41 and wheel hub assembly to the next process.

[0073] Repeat the above steps to install the next set of tires and rims.

[0074] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
